Advanced Exposure Modes for Your Nikon D3100 Digital Camera

To really take creative control with your Nikon D3100, step up to one of these four exposure modes, which enable you to adjust aperture (f-stop) to manipulate depth of field (the zone of sharp focus) and to adjust shutter speed to determine whether moving objects appear sharply focused or blurry. You also gain access to some features not available in the fully automatic modes, such as the option to adjust flash power and tweak white balance.
